SPRING FOR VEHICLES.

i Specification of Letters Patent.

Patented May 6, 1913?.

Application filed July 27. 1911. Serial no. 640,501.

Be it known that 1, JOHN A. MOAN LTY, United States, now residing at Indianapolis, in the county of Marion and State of Indiana, haveinvented certain new and useful Improvements in Springs for Vehicles, of which the following is a I specification.

The object of my invention is to increase the vertical range. of movement of the axle to a greater degree or beyond the combined This object is obtained through the medium of a spring fulcrumed to its ends in such double or treble the range of the axle over the compression of the springs.

In the drawing :-Figure 1 is a side elevation of a vehicle with my spring applied, and Fig. :2 is a side elevation of a chassis, parts shown in dotted outline.

A represents the front of the vehicle and B the rear.

1 represents the body of the vehicle having turned down portions 2 and 3 at the front and rear ends.

1 and 5 are depending brackets or arms, the bracket 5 being longer than the bracket l.

6 is the wheel of the vehicle indicated in dotted lines and 7 the axle, which may be of any approved construction.

The axle spring 8 is secured to the axle by means of the clips 9 and. 10, the clips 9 being secured the nuts 11. The clip 10 is provided with a yoke 12 surrounding the axle 7, said yoke being provided with shackles ,13 and 1 1 which are hinged thereto.

15 is a spring which is shown in Fig. 1 as a bow spring, the front end of which is connected to the body of the vehicle by means of the arm 4: with which itvhas a hinge joint 16. The rear end of the spring 15 is connected by means of the hinge joint 17 to the shackle 13.

18 is-a spring member similar to 15, the forward end of which is connected by means of the hinge joint 19 to the shackle 1 1, while its rearward end is connected by a hinge joint to the shackle 20, which in turn is swung on the depending portion 3 of the body. In this connection, it will be noted that this spring 18 is hung upon a way as to shackles at eachend, whereby it is enabled being broken away with the WllGGlS' to the clip 10 by means of .ing the other end to the axle,

to move axially bodily relative tothe arts and the body of the vehicle, while the spri'eg' 15 is held against axial bodily movement by reason of its hinge connection with the arm 1.

The axle spring is secured at itsends to the springs 18 and 15 respectively, by means of the clip 21 which is fixedly secured to the springs 15 and 18 by means of the bolts 22.

In the leverage system of the springs, the ends of the axle spring serve as fulcrums for the springs 15 and 18, so that when the hinges 21 are central of the springs 15 and 18 the vertical range of movement of the axle is double the combined compression of the, axle spring and the springs.

It will be understood that. if the hinges 21 are mounted on the springs 15 nearer their inner ends than their outer ends the vertical range of the axle will be greater than double, the combined compression of the spring 8 and that of 15 and 18 collectively.

If hinged farther from the axle than their centers the range of axle will be less than double the compression of the springs.

With the hinges central they double the spring compression. One third out from the axle they would vibrate three inches to one inch in spring compression.

1 claim 1.1In a vehicle, the combination with the body and axle, of a bow spring, one end of which is hinged to the body and its other end connected to the axle by a shackle, a second spring, thereof to the body, and a shackle connectand a third bow spring connected to the axle with its ends hinged to an intermediate point on the first and second springs.

2. In a vehicle, the combination with the body and axle, of a spring secured to the axle and extending rearwardly therefrom with its rear end secured to the body against spring ext-ending bodily axiaLmovement, a

and shackles conforwardly from the axle, necting its endsto spectively and permitting said spring to move bodily axially independently of a relative movementof the body of the ve hicle, and an axle spring secured to the axle at its center with its ends hinged at an intermediate point to the other springs, whereby the temporary stoppage of the wheel of the vehicle due to an obstruction will be taken a shackle connecting one end the axle and body reup by compression on the rearwardly ex- I center to the other end of the central bow, tending spring and by the bodily axial one end of which is hinged to the vehicle movement of the forwardly extending spring permitted by the shackles.
